Description

Technical Field

[0001] This invention relates to an automatic clamping welding device for a laser welding machine, and particularly to an automatic clamping welding device for a laser welding machine, belonging to the field of welding technology. Background Technology

[0002] The hoe is a highly efficient tool designed specifically for agricultural operations. This implement consists of three parts: a claw hook, a hoe head, and a ring. The claw hook not only increases the depth and efficiency of tilling and loosening the soil but also easily handles various complex soil conditions, making it particularly suitable for hard soil or land requiring meticulous cultivation. The hoe head is designed to renovate relatively soft soil and also clear weeds growing alongside crops, ensuring better nutrient absorption for the crops. Therefore, it is widely used in small farmlands such as vegetable gardens and orchards for tilling, weeding, loosening soil, and ditching / ridge-making.

[0003] In the existing technology, the hoe and the claw hook are first fixed to the outside of the ring by corresponding clamps, and then the hoe and the claw hook are welded to the outside of the ring by hand welding gun. However, according to actual production needs, the welding steps in the existing technology are not very convenient. Therefore, there is an urgent need to improve the automatic clamping welding device of the laser welding machine to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic clamping and welding device for a laser welding machine. By setting two sets of mutually symmetrical support mechanisms, the two sets of symmetrical support mechanisms move relative to each other. Therefore, the support mechanism supports the inner side of the ring and pushes the welding mechanism. At this time, the welding gun set in the welding mechanism moves out of the protective cover. Then, the motor drives the shaft and the connecting plate to rotate, which in turn drives the positioning rod and the magnetic suction frame to rotate. The magnetic suction frame picks up the outer side of the welding gun and slides along the inner side of the track frame. The shaft transmits power to the welding mechanisms on both sides of the ring at the same time. At this time, it is convenient to weld and fix the hoe and the claw hook on both sides of the ring at the same time.

A second spring is spirally wound around the outer side of each of the two sets of symmetrically arranged sliding rods. The retaining ring and the fixing plate abut against the outer side of the second spring. A lever is rotatably connected to the end of each of the two sets of symmetrically arranged sliding rods away from the retaining ring. A fulcrum is rotatably connected to the outer side of one set of levers. The fulcrum is fixedly connected to the outer side of the fixing plate.

[0008] Preferably, a set of protective covers is provided at both ends of the fixing plate. Two sets of symmetrical baffles are provided on the outer side of the set of protective covers.

[0009] Preferably, a set of track frames is provided on the other side of one set of protective covers. A magnetic suction frame is placed on the inner side of the track frame. The magnetic suction frame is used to pick up the outside of the welding gun. A positioning rod is provided on the outer side of the magnetic suction frame. A connecting plate is fixedly connected to the end of the positioning rod away from the magnetic suction frame. The inner side of the connecting plate is coaxially connected to the connecting shaft.

[0010] Preferably, a first pulley is threadedly connected to the outer side of one set of slide rods, and a second pulley is connected to the outer side of the first pulley via a belt. The first pulley and the second pulley are rotatably connected to one side of the fixed plate.

[0011] Preferably, two sets of symmetrical rotating plates are provided on the outer side of the second pulley, and a cleaning brush is provided at the ends of the two sets of symmetrical rotating plates that are far apart from each other.

[0015] The present invention has at least the following beneficial effects:

[0016] 1. Two sets of symmetrical support mechanisms are each equipped with a movable plate. The movable plates drive their respective welding mechanisms to move relative to each other via electric actuators. At this time, the support head is located inside the ring, and the shafts of the two sets of symmetrical welding mechanisms are connected to each other. Since the hinge head is fixedly connected to the movable plate via a fixed rod, the connected shaft passes through the movable plate and the outer side of the fixed plate along the inner side of the hinge head. The support head pushes the swing arm to swing outside the hinge head via the outer support rod, so that the swing arm opens and abuts against the inner side of the ring, fixing the ring. The opened swing arm pushes the retaining ring to move towards the movable plate. The retaining ring pushes the lever through two sets of symmetrical sliding rods. The lever and the fulcrum cooperate with each other, so that the lever tilts up. At this time, the welding gun is attracted by the electromagnet, and the lever presses the electromagnet to push the welding gun out of the inner side of the protective cover.

[0017] 2. When the two sets of mutually symmetrical support mechanisms move in opposite directions, the first spring on the outside of the shaft pushes the hinge head against the support head, and the support head drives the shaft to reset. At the same time, the support head pulls the support rod and drives the swing rod to swing outside the hinge head. The swing rod releases the fixation of the ring. At this time, the second spring pushes the retaining ring against the fixing plate to reset. At this time, the two sets of mutually symmetrical sliding rods pull their respective levers to swing inside the fulcrum frame. At the same time, the welding gun is attracted to the inside of the protective cover by the electromagnet. Attached Figure Description

[0029] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0030] like Figure 1 , Figure 9As shown, the automatic clamping and welding device for a laser welding machine provided in this embodiment includes a first placement frame 101, two sets of second placement frames 102, and a support frame 2 respectively provided on the top of a support plate 1. The first placement frame 101 is used to support the hoe, the two sets of second placement frames 102 are used to support the claw hook, and the support frame 2 is used to support the ring. Two sets of mutually symmetrical support mechanisms 6 are provided on the outside of the support frame 2. The two sets of mutually symmetrical support mechanisms 6 can move relative to each other to support and fix the inner side of the ring. Each of the two sets of mutually symmetrical support mechanisms 6 includes a welding mechanism 7, which is used to weld the hoe and claw hook on both sides of the ring.

[0031] This agricultural tool consists of three parts: a claw hook, a hoe, and a ring.

[0032] Furthermore, each of the two sets of mutually symmetrical welding mechanisms 7 includes a set of shafts 61. A support head 62 is fixedly connected to one end of the outer side of the set of shafts 61. A connecting shaft 718 is slidably connected to the inner side of the set of shafts 61. Four sets of mutually symmetrical support rods 63 are rotatably connected to the outer side of the support head 62. A hinge head 64 is slidably connected to the outer side of the set of shafts 61. Four sets of mutually symmetrical swing rods 65 are rotatably connected to the outer circumference of the hinge head 64. A groove 651 is opened at the end of the four sets of mutually symmetrical swing rods 65 away from the hinge head 64. The end of the support rod 63 away from the support head 62 is slidably connected to the inner side of the groove 651. A first spring 66 is spirally wrapped around the outer side of the shaft 61. The support head 62 and the hinge head 64 respectively abut against the outer side of the first spring 66. Three sets of fixed rods 641 are fixedly connected to the side of the hinge head 64 away from the first spring 66. A movable plate 601 is fixedly connected to the other end of the three sets of fixed rods 641.

[0033] One set of shafts 61 has a socket 719 at one end of the inner side of the connecting shaft 718, and another set of shafts 61 has a plug 720 at one end of the inner side of the connecting shaft 718. The plug 720 is inserted into the socket 719. The outer side of the moving plate 601 has an electric push rod 4. The end of the electric push rod 4 away from the moving plate 601 is fixedly connected to a connecting frame 3. The lower side of the connecting frame 3 is fixedly connected to the outer side of the support frame 2. The inner side of the support frame 2 has a stabilizing rod 5. The outer side of the stabilizing rod 5 is slidably connected to the inner side of the moving plate 601. The end of the stabilizing rod 5 is fixedly connected to the inner side of the connecting frame 3.

[0034] In this method, power is supplied to the electric actuator 4, and the two sets of mutually symmetrical welding mechanisms 7 move relative to each other via their respective moving plates 601. At this time, the support head 62 moves to the inner side of the ring, and the two sets of mutually symmetrical welding mechanisms 7 drive their respective support heads 62 to connect. At this time, the shafts 61 set by the two sets of mutually symmetrical welding mechanisms 7 extend outward along the inner side of the moving plate 601. The extended shafts 61 simultaneously drive the support head 62 to move. At this time, the support head 62 slides inside the slide groove 651 via the support rod 63. The support rod 63 pushes the swing rod 65 to open outside the hinge head 64, and the opened swing rod 65 supports the... Inside the ring, the plug 720 and socket 719 of the inner connecting shaft 718 of one set of shafts 61 are connected. Through the cooperation of the socket 719 and the plug 720, power is transmitted to the welding mechanism 7 inside the two sets of mutually symmetrical support mechanisms 6. When the two sets of mutually symmetrical support mechanisms 6 move away from each other, the first spring 66 on the outside of the shaft 61 pushes the support head 62 to reset. This helps the support head 62 to pull the swing arm 65 through the support rod 63 to release the ring from fixation. Then, the stability rod 5 increases the stability of the moving plate 601 moving back and forth.

[0035] Furthermore, the welding mechanism 7 includes a retaining ring 71, one side of which is fitted against the outer side of four sets of symmetrically arranged rocker arms 65. Two sets of symmetrically arranged sliding rods 72 are provided on the outer side of the retaining ring 71. A fixed plate 73 is slidably connected to the outer side of the two sets of symmetrically arranged sliding rods 72. A second spring 74 is spirally wound around the outer side of each set of symmetrically arranged sliding rods 72. The retaining ring 71 and the fixed plate 73 respectively abut against the outer side of the second spring 74. A lever 75 is rotatably connected to the end of each set of symmetrically arranged sliding rods 72 away from the retaining ring 71. A fulcrum 76 is rotatably connected to the outer side of each lever 75. The fulcrum 76 is connected to the fixed plate 74. The outer side of the fixed plate 73 is fixedly connected, and the inner side of the fixed plate 73 is slidably connected to the outer side of the shaft 61. An electromagnet 751 is rotatably connected to one end of a lever 75 away from the slide bar 72. A set of protective covers 77 is provided at both ends of the fixed plate 73. Two sets of symmetrical baffles 78 are provided on the outer side of the set of protective covers 77. The electromagnet 751 slides inside the protective cover 77. A welding gun 752 is placed inside the protective cover 77. The electromagnet 751 is used to attract the welding gun 752. Two sets of mutually symmetrical baffles 753 are provided on the outer side of the welding gun 752. The baffles 753 slide inside the baffles 78.

[0036] In this method, the open swing arm 65 simultaneously pushes the retaining ring 71 to move towards the moving plate 601. The retaining ring 71 pushes its respective lever 75 through two sets of mutually symmetrical sliding rods 72. The lever 75 presses the electromagnet 751 through the fulcrum frame 76 to slide inside the protective cover 77. The electromagnet 751 moves out of the protective cover 77 by picking up the welding gun 752. Two sets of mutually symmetrical stop blocks 753 on the outside of the welding gun 752 slide inside the stop groove 78 to prevent the welding gun 752 from rotating when it moves out of the protective cover 77. When the support mechanism 6 is reset, the retaining ring 71 is pushed back to its original position by the second spring 74. At this time, the sliding rod 72 pulls the lever 75 and picks up the welding gun 752 inside the protective cover 77 through the electromagnet 751.

[0037] One of the protective covers 77 has a set of track frames 79 on the other side. A magnetic suction frame 712 is placed inside the track frame 79. The magnetic suction frame 712 is used to pick up the outside of the welding gun 752. A positioning rod 711 is provided on the outside of the magnetic suction frame 712. A connecting plate 710 is fixedly connected to the end of the positioning rod 711 away from the magnetic suction frame 712. The inside of the connecting plate 710 is coaxially connected to the connecting shaft 718. A motor 8 is provided at one end of the connecting shaft 718. A mounting frame 9 is provided on the outside of the motor 8. The mounting frame 9 is fixedly connected to the outside of the moving plate 601.

[0038] In this method, when the welding gun 752 slides out of the protective cover 77, the welding gun 752 is located inside the track frame 79 and is attracted to the outside of the welding gun 752 by the magnetic suction frame 712. The motor 8 is started, which simultaneously drives the connecting shaft 718 and the connecting plate 710 to rotate. The connecting shaft 718 facilitates the output of power to the welding mechanism 7 on both sides of the ring. At this time, the connecting shaft 718 transmits power to the connecting plate 710, and then drives the magnetic suction frame 712 to rotate through the positioning rod 711. At this time, the welding gun 752 attracted by the magnetic suction frame 712 slides along the inside of the track frame 79, which facilitates the welding gun 752 to weld the hoe and claw hook on the outside of the ring at the same time.

[0039] Furthermore, a first pulley 713 is threadedly connected to the outer side of one set of slide rods 72, and a second pulley 715 is connected to the outer side of the first pulley 713 via a belt 714. The first pulley 713 and the second pulley 715 are rotatably connected to one side of the fixed plate 73. Two sets of mutually symmetrical rotating plates 716 are provided on the outer side of the second pulley 715, and a cleaning brush 717 is provided at the ends of the two sets of mutually symmetrical rotating plates 716 that are far apart from each other.

[0040] In this method, when the retaining ring 71 moves toward the moving plate 601, one of the sliding rods 72 pushes the first pulley 713 connected by threads to rotate outside the fixed plate 73, which is beneficial for the belt 714 to drive the second pulley 715 to rotate. At the same time, the second pulley 715 drives two sets of mutually symmetrical rotating plates 716 to rotate. Then, the rotating plates 716 drive the cleaning brush 717 to clean the weld seam where the outer side of the ring connects with the hoe and the claw hook.

[0041] like Figure 1 , Figure 9As shown, the principle of the automatic clamping welding device for a laser welding machine provided in this embodiment is as follows: First, the hoe, the ring, and the claw hook are placed simultaneously on the upper side of the first placement frame 101, the second placement frame 102, and the support frame 2, respectively. By supplying power to the electric push rod 4, the two sets of mutually symmetrical support mechanisms 6 move relative to each other through their respective moving plates 601. The support mechanism 6 is located inside the ring. The two sets of mutually symmetrical support mechanisms 6 drive their respective support heads 62 to engage with each other. Since the hinge head 64 is fixedly connected to the moving plate 601 through the fixed rod 641, at this time the support head 62 pushes the shaft rod 61 to extend along the inner side of the hinge head 64 to the outer side of the moving plate 601. On the side, the support head 62 pushes the swing rod 65 to open outside the hinge head 64 via the support rod 63. The opened swing rod 65 is supported on the inner side of the ring and fixed to the ring. At the same time, the opened swing rod 65 pushes the retaining ring 71 to move towards the moving plate 601. The retaining ring 71 pushes two sets of mutually symmetrical sliding rods 72 to extend to the outside of the fixed plate 73. The extended sliding rods 72 push the lever 75 to tilt up. At the same time, one set of sliding rods 72 pushes the first pulley 713, which is connected by a thread, to rotate outside the fixed plate 73. The first pulley 713 drives the second pulley 715 through the belt 714. The rotating second pulley 715 simultaneously transmits power to the two sets of mutually symmetrical rotating plates 716. The power is transmitted, and at this time, the two sets of symmetrical rotating plates 716 drive their respective cleaning brushes 717 to rotate, cleaning the weld seam where the outer side of the ring meets the hoe and claw hook. Under the action of the fulcrum frame 76, the lever 75 presses the welding gun 752 through the electromagnet 751. At this time, the welding gun 752 moves out of the inner side of the protective cover 77, and at the same time, the stop block 753 slides along the inner side of the stop groove 78. When the welding gun 752 is located inside the track frame 79, the stop block 753 will fit against one side of the track frame 79, thus facilitating the magnetic suction frame 712 to pick up the outer side of the welding gun 752. When the support head 62 drives the support rod 63 to open the swing rod 65, at this time, one of the sets of shaft rods 61 inside The socket 719 on the side connecting shaft 718 is connected to the plug 720 on the inner connecting shaft 718 of another set of shafts 61. The end of one set of shafts 61 away from the plug point is coaxially connected to the connecting plate 710 and the motor 8 is plugged in. At this time, the motor 8 is powered. At this time, the welding mechanism 7 of each of the two sets of mutually symmetrical support mechanisms 6 will simultaneously receive the power of the motor 8. The motor 8 drives the positioning rods 711 at both ends to rotate through the connecting plate 710. The positioning rods 711 then drive the magnetic suction frame 712 to rotate. The magnetic suction frame 712 picks up the welding gun 752 and slides along the inner side of the track frame 79, and simultaneously welds the hoe and claw hook connected to the outer side of the ring.
